Abstract

ObjectiveTo analyze the changes in children's height, weight, BMI and rates of stunting and overweight and obesity over three periods: 1986–1987, 1996–1998, and 2023 for the community of Yalcoba in the Yucatan Peninsula.Material and MethodsFour hundred forty (6‐to‐15 years) children measured in 2023 were compared with data obtained in 1986–1987 (n = 675) and 1996–1998 (n = 628). Z‐scores of height and BMI were calculated to estimate percentages of stunting and high BMI‐for‐age (overweight and obesity). Comparisons of anthropometric parameters by sex and age groups between years of measurement were performed through one way ANOVAs.ResultsDifferences in anthropometric parameters were significant in all age groups of both sexes. Boys measured in 2023 were, on average, 6.4 and 3.3 cm taller than boys measured in the 1980s and 1990s, respectively. Increases in girls were 12 and 7.3 cm, respectively. Average increases in weight of boys measured in 2023 were 7.9 kg compared to the 1980s and 5.8 kg compared to 1990s. Average increases in girls measured in 2023 were 11.3 kg compared to the 1980s, and 7.6 kg compared to the 1990s. Stunting between the 1980s and 1990s decreased by 15 percentage points and between the 1990s and 2023 decreased by 47 percentage points. The percent of children deemed overweight/obese during these periods increased from 8 to 12–50 by 2023.ConclusionResults reflect the overall trends seen in the Yucatan where stunting has decreased substantially but the numbers of overweight/obese youths have increased dramatically in the past 30 years.

雅尔科瓦玛雅村增长的周期性变化：1986-2023 年

材料与方法将 2023 年测量的 4400 名儿童（6 至 15 岁）与 1986-1987 年（675 人）和 1996-1998 年（628 人）获得的数据进行比较。通过计算身高和体重指数的 Z 值，估算出发育迟缓和高体重指数（超重和肥胖）儿童的百分比。通过单因素方差分析，比较了不同测量年份的性别和年龄组的人体测量参数。2023 年测量的男孩比 20 世纪 80 年代和 90 年代测量的男孩平均身高分别增加了 6.4 厘米和 3.3 厘米。女孩分别增加了 12 厘米和 7.3 厘米。2023 年测量的男孩体重与 20 世纪 80 年代相比平均增加了 7.9 千克，与 20 世纪 90 年代相比平均增加了 5.8 千克。2023 年测量的女孩平均体重比 20 世纪 80 年代增加了 11.3 千克，比 20 世纪 90 年代增加了 7.6 千克。发育迟缓率在 20 世纪 80 年代和 90 年代之间下降了 15 个百分点，在 20 世纪 90 年代和 2023 年之间下降了 47 个百分点。结论：这些结果反映了尤卡坦半岛的总体趋势，即发育迟缓率大幅下降，但超重/肥胖青少年的人数在过去 30 年中急剧增加。

期刊介绍： The American Journal of Human Biology is the Official Journal of the Human Biology Association. The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field. The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology. Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification. The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
